Subject: [PATCH net-next v3 0/1] net/tls: Combined memory allocation for decryption request
This patch does a combined memory allocation from heap for scatterlists,
aead_request, aad and iv for the tls record decryption path. In present
code, aead_request is allocated from heap, scatterlists on a conditional
basis are allocated on heap or on stack. This is inefficient as it may
requires multiple kmalloc/kfree.
The initialization vector passed in cryption request is allocated on
stack. This is a problem since the stack memory is not dma-able from
crypto accelerators.
Doing one combined memory allocation for each decryption request fixes
both the above issues. It also paves a way to be able to submit multiple
async decryption requests while the previous one is pending i.e. being
processed or queued.
